"After conducting an extensive review of multiple IP/MPLS/Ethernet/Evolved Packet Core equipment suppliers, we're pleased to extend long-standing relationships with Alcatel-Lucent, Cisco and Juniper Networks," said Tim Harden, president of AT&T's Supply Chain and Fleet Operations organization. "AT&T's selection of these three industry-leading suppliers as domain suppliers showcases our ongoing commitment to meet the quality expectations of our customers today, while preparing for the demands of tomorrow."

AT&T launched its domain supplier program last year to facilitates a more collaborative relationship with its equipment and software suppliers.

In January, AT&T announced total 2010 capital expenditures were expected to be between $18 billion and $19 billion, a big chunk of which will no doubt fall into Cisco, Alcatel-Lucent and Juniper's coffers.
